Another term in the right-hand side of Equation (4.12) can be added in terms of z, the coordination number of the lattice, and a a symmetry number. Coleman and Painter [4-6] assnmed that the association model to describe hydrogen bonding interactions can be used and added to the contribution to the Flory-Hnggins equation for the free energy of mixing ... 

Coleman and Painter have reported that the miscibility in hydrogen bonded blends is primarily dictated by the balance between unfavorable physical and favorable chemical interactions [187,190]. They have developed a model, called the association model, that makes use of the self- and inter-association equilibrium constants...
